SPECIFICATION forming part of Letters Patent No. 705,185, dated July 22,1902.

Application filed January 71 1901. $erial No. 42,304.- (No model.)

that class of constructions whereby the hub of a Wheel is secured to thespindle of the axle; and the objects of these improvements are, first,to oil or grease the spindle without removing the wheel therefrom, and,second, to prevent the wheel from accidentally becoming detached fromthe spindle.

The invention consists in the construction, arrangement, and combinationof parts, as hereinafter fully described and then pointed out in theclaims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a side view of a spindle of an axle and a longitudinalsectional view of a hub and an axle-box Figs. 2 and 3 are longitudinalsections of modified constructions of the inner end of the axle-box;Fig. 4:, a similar section of a modified construction of the outer endof the axle-box, and Fig. oan outerend view of a wheel-hub provided withan axle-box of said modified construction. Fig. 6 is a face view of thebearing-ring, and Fig. 7 a face view of the.

ring-nut.

Similar numerals indicate like parts throughout the several views.

Referring to the details of the drawings, 1 indicates the hub of awheel; 2, the pointband; 3, the butt-band; 4, the spokes, and 5 theaxle.

In Fig. 1, 6 refers to the spindle of the axle,

having near its inner end a spherical boss 7 hemisphere of boss 7. Abearing-ring 13, of metal or any other suitable material and located inchamber 12, embraces the butt of the spindle and has inits inner face acurved socket 1 1, that engages and forms a bearing for the outerhemisphere of boss 7. The outer end of the wall of chamber 12 isthreaded, as

seen at 15, and through this threaded portion a ring-nut 16 is engagedwith the axle-box. The inner face of ring-nut 16 is hollowed out, andlocated therein and extending entirely around spindle 6 is a series ofcoiled springs 17, each of which has one end bearing against the bottomof the cavity in. the ringnut and the other end bearing against the backof bearing-ringlb, thus forming a resilientcushion between the ring-nutand the bearing-ring. These springs may be entirely separate the onefromthe other,0r they may be connected as are the springs of beds. Thepressure of springs 17 on bearing-ring 13 holds the latter in closecontact with boss 7 and compels it to take up the wear of the parts. Thescrew-thread 15 in the inner end of the axlebox is extended inward farenough, as shown at 18, to permit the tension of springs 17 to beincreased. Any elastic body suitable for the purpose may be substitutedfor the springs.

In Fig. 6 is a face viewof I bearing-ring 13 in place in chamber 12. ofthe axle box.

( Shown in section.) As seen in this figure,

bearing ring 13 is divided into two sections at 19, and on the peripheryof each section is a transverse rib 20, that engages correspondinggrooves 21 in the inner wallof chamber 12, whereby said bearing-ring isrevolved with the axle-box. Instead of two, bearing-ring 13 can bedivided intoas many more sections as may be deemed expedient.

In Fig. 7 is shown a face view of ring-nut 16. This nut may be dividedin various waysinto two sections hinged together at 22, as shown by fulllines, and meeting, as shown by broken line 23, or. the lines of the nutmay be continuous at the topfas indicated by broken lines 24, and asection 25 be cut out below of sufficient width to allow the said nut totake over the axle, section 25 being connected with the body of thering-nut by dovetail joints 26, or it may be divided in any other waysuitable for the urpose, as the manner of dividing the ring-nut does notform any part of this invention.

In Fig. 2 is illustrated a modification in the inner end of theaxle-box, wherein the chamber 27 thereof is formed by walls 28, tangentto the walls 29 of the socket of said box. With this construction thethickness of bearing-ring 30 need not be so great as that of thebearing-ring shown in Fig. 1, for the peripheral portion 31 of bearing-rin g 13 is not needed to enable bearing-ring 30 to fill the chamber27. In this device the ring-nut embraces the end of the axle-box, asshown at 32.

In Fig. 3 is illustrated a further modification in the arrangement ofthe inner end of the axle-box, wherein the curves of the boss 33longitudinally of its spindle 34 are elliptical instead of being arcs ofcircles, as are those shown in Figs. 1 and 2. The bearingring 35 is ofsimilar construction to that shown in Fig. 2, and the chamber 36,wherein it is placed, is formed as is the chamber 27; but the portion 37of the axle-box forming the socket for the ring-nut 38 is enlarged, sothat when'said nut is in place the hollow seat 39 for the springs 17 isof the same diameter as that of chamber 36.

In Fig. 1 the part 40, closing the outer end of the axle-box, isintegral therewith. In Fig. 4, however, the outer end 41 is closed by ascrew-cap 42, having a rim 43 on its inner end, whereby outward movementof the hub on the axle-box is prevented.

The back of the ring-nut forms a wall 44:, that prevents the escape ofany of the lubricant in the chamber of the axle-box lying below thecentral opening in said ring-nut.

In these constructions the opening through which the lubricant is fed tothe axle is placed in the center of the end of the axle-box, whereby asthe wheel revolves there is always an outer wall preventing the escapeof said lubricant. The boss on the spindle and the socket in theaxle-box engaged thereby form a ball-and-socket joint, providing theeasiest possible shoulder-bearing against the outward thrust of thespindle, while the bearing-ring, the ring-nut, and the springs betweenthem hold the boss snugly to its seat, take up the Wear, and preventlooseness and rattling of the parts. The advantage of the concave shapeof the sockets and of the convex shape of the bosses is that they enablethe bosses under the pressure exerted thereon to take up the wear of thecontacting parts a both vertically and horizontally.

I do not restrict myself to the details of the construction herein shownand described, as it is obvious that many alterations might be madetherein without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination, an axle-box provided with a forwardly-extendingconcave socket having a rear opening, a spindle, a forwardlyextendingconvex boss on the spindle and adapted to enter said rear opening andengage the socket, and means for maintaining the boss in engagement withthe socket, for the purpose specified.

2.
